Follow these steps to solve system faults:
To do...
Enter system view
Specify the system fault solving
method for the MPU
NOTE:
•
Rebooting the MPU reboots the firewall.
If an interface module encounters software faults, the solving method is always reboot, which reboots the
•
failed module.
When system faults occur, the system fault solving method applies to only the failed module, and
•
rebooting the module does not interrupt the other modules.
Viewing the system fault solving method
Use the display system-failure command to display the system fault solving method.
<Sysname> display system-failure
System failure handling method: reboot
Saving the current configuration of the firewall
You can save the current configuration of the firewall in one of the following methods:
•
Fast saving: Executing the save command without the safely keyword. This mode saves the file more
quickly but is likely to lose the existing configuration file if the firewall reboots or the power fails
during the process. The fast saving mode is suitable for environments where the power supply is
stable.
Safe saving: Executing the save command with the safely keyword. The mode saves the file more
•
slowly but can retain the configuration file in the firewall even if the firewall reboots or the power
fails during the process. The safe saving mode is preferred in environments where a stable power
supply is unavailable or remote maintenance is involved.
Follow these steps to save the current configuration of the firewall:
To do...
Save the current configuration to the specified file, but the
configuration file will not be set as the file for the next startup
Save the current configuration to the root directory of the
storage medium of the MPU and specify the file as the startup
configuration file that will be used at the next system startup
NOTE:
•
The configuration file must be with extension .cfg.
During the execution of the save command, the startup configuration file to be used at the next system
•
startup may be lost if the firewall reboots or the power supply fails. In this case, the firewall will boot with
the factory defaults, and after the firewall reboots, you need to re-specify a startup configuration file for
the next system startup.
Use the command...
system-view
system-failure { maintain |
reboot }

Optional
reboot by default for the MPU.
